标题:Poly-diisopropenyl benzene synthesis
发明人：JALICS GEORGE
权利人:GOODYEAR TIRE & RUBBER
摘要:It has been unexpectedly found that meta-diisopropenyl benzene can be polymerized into poly-m-diisopropenyl benzene with a relatively narrow molecular weight distribution and with only a small degree of crosslinking (gel formation) if done in the presence of at least one alpha-olefin containing from 2 to 12 carbon atoms in tetrahydrofuran (solvent) at low temperatures employing an alkyl lithium initiator. The poly-m-diisopropenyl benzene produced by employing this technique has an isopropenyl moiety on almost every diisopropenyl benzene repeat unit in the polymer. This polymer is particularly useful since its pendant isopropenyl groups can be further reacted with other compounds leading to polymers with various functionalities. This technique can also be employed in the synthesis of copolymers containing repeat units derived from meta-diisopropenyl benzene and one or more other monomers. The copolymers synthesized using the process of this invention contain an essentially quantitative number of unreacted isopropenyl groups on the meta-disisopropenyl benzene repeat units in the polymer chain.

标题:Process for the preparation of beta-gamma unsaturated esters
发明人：BURKE PATRICK MICHAEL
权利人:DU PONT; DSM NV
摘要:A process for the carbonylation of allylic butenyl ether (e.g., methyl crotyl ether, 3-methoxybutene-1 and mixtures thereof) or mixture of butadiene and alcohol (e.g., methanol) and production of beta-gamma unsaturated carboxylic acid esters (e.g., methyl-3-pentenoate) utilizing a rhodium-containing catalyst (e.g., dicarbonylacetylacetonate rhodium(I) or the like) promoted with an iodide-containing compound (e.g., HI, AlI3, SnI4, TiI4, CrI3, and CoI2 or the like). Such a process is particularly useful in the production of difunctional monomers and intermediates in the synthesis of adipic acid. The representative reaction showing (a) butadiene in the presence of methanol under catalytic reaction conditions producing the 3-methoxybutene-1 intermediate (a positional isomer of methyl crotyl ether) which is then combined with carbon monoxide to produce methyl pentenoate is illustrative of the overall carbonylation.

摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题:Removal of acrylonitrile from latex with saturated heterocyclic amines
发明人：SENYEK MICHAEL L
权利人:GOODYEAR TIRE & RUBBER
摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with saturated 6 to 7 membered ring heterocyclic amines. These amines react with acrylonitrile by a nitrogen-cyanoethylation reaction which results in the formation of a tertiary amino linkage.
